Yeah, I can see that point being made for NCAA because there are 120 teams(?) with 100's of different fight songs. But for the NFL, it's a different deal because most of what you hear in the NFL is the same popular music being played at every stadium for every team (except for team specific chants or the team theme song). Back when 2K had custom stadium sounds for 2K5, you just put their own music in and people loved it.
I like that Madden has included songs that we typically hear at NFL stadiums, but I just can't see how that can ever beat end user customization. What if I hate "Right Now" by Van Halen playing during kickoffs and would rather have "Start me up" by the Rolling Stones? Without custom event-based trax like NCAA has, I have no choice in the matter.
